Abstract

The invention provides an earthquake alarm which comprises an induction device and an alarm circuit and is capable of giving acousto-optic alarm. The earthquake alarm is characterized in that the induction device comprises a supporting frame fixed on a bottom plate and a magnet suspended on the supporting frame; the alarm circuit comprises a power supply, a reed pipe arranged below the magnet and an acousto-optic alarm device arranged in the circuit, wherein the reed pipe is accessed to the circuit in a form of a normally-closed point. The alarm comprises the induction device and the alarm circuit, and realizes the rapid induction on earthquake and caution function for people in a seismic center. A relay J playing a self-locking function is arranged in the alarm circuit to ensure that an alarm signal is continuous.

Description

Earthquake warner

Technical field

The present invention relates to a kind of earthquake warner, in particular, relate in particular to a kind of earthquake warner that comprises induction installation and warning circuit and can carry out sound and light alarm.

Background technology

When earthquake took place, the most basic phenomenon was the continuous shaking of base plate, and principal character is significantly to rock.The people of seismic region at first felt less vibrations sometimes before feeling big rocking.This is because seismic event transmits the cause that compressional wave at first arrives to base plate in ground.Shear wave then produces the rocking of horizontal direction of large amplitude, is the main cause that causes geologic hazard.But, if just begun that time of rocking, just there is a kind of alarm device to remind our earthquake at base plate, so just can reduce the infringement that earthquake causes.Yet the present electronic earthquake warning horn that uses, circuit theory and structure are very complicated, make that their price is very expensive, are not easy to popularize in urban and rural households.

Summary of the invention

The present invention has overcome the shortcoming of above-mentioned technical matters, and a kind of earthquake warner that comprises induction installation and warning circuit and can carry out sound and light alarm is provided.

For achieving the above object, the present invention has adopted following technical scheme:

Earthquake warner of the present invention, comprise induction installation and warning circuit, its special feature is: described induction installation comprises bracing frame that is fixed on the base plate and the magnet that hangs on the bracing frame, described warning circuit comprises power supply, be arranged at the tongue tube of magnet below and be arranged at acoustic-optic alarm in the circuit, in the form place in circuit of described tongue tube with normally closed point.Vibrations when the bracing frame that fixes with base plate can be used to respond to earthquake and just arrived, and this vibrations are converted into the swing of magnet, and then change the state of tongue tube in circuit; If earthquake occurs in night, adopt acoustical signal and light alarm, help evoking people's attention more.

Earthquake warner of the present invention, described acoustic-optic alarm comprise bulb and are provided with the loudspeaker of music-integrating block.The light that bulb sends can attract much attention more, and can also realize illumination functions, and particularly more favourable for the abovestairs resident that lives, electric power system tends to interrupt during owing to earthquake, adopts bulb can realize the illumination functions that electric torch is the same; After the people of hand-held shake alarm is buried in the ruins, if alarm does not damage, also can make the rescue worker find to bury personnel in the very first time, increased the probability that buried personnel are rescued.

Earthquake warner of the present invention also comprises relay J, and the coil of this relay J is in parallel with acoustic-optic alarm after connecting with tongue tube again; Be in parallel the normal battle of tongue tube and relay J; Be in series the normal battle of acoustic-optic alarm and relay J.The purpose that increases a relay J is in order to make circuit realize auto-lock function, even magnet contacts by leaving to become with tongue tube, warning circuit is disconnected, and can continue to report to the police.

Earthquake warner of the present invention, described magnet is connected with bracing frame by cycloid.Magnet with after bracing frame is connected, just can form a pendulum by cycloid, helps separating of in the process of earthquake magnet and tongue tube.

The invention has the beneficial effects as follows: warning horn of the present invention comprises induction installation and warning circuit, has promptly realized the quick induction to earthquake, has also realized the good warning function to the earthquake centre people; By the induction installation of forming with base plate bracing frame that fixes and the magnet that is connected with bracing frame, help more in the vibrations of very first time induction base plate; In warning circuit, also the relay J that plays self-locking action can be set, make alerting signal uninterrupted continuously.

Description of drawings

Fig. 1 is the circuit theory diagrams of first kind of embodiment of the present invention;

Fig. 2 is the circuit theory diagrams of second kind of embodiment of the present invention;

Among the figure: 1 bracing frame, 2 cycloids, 3 magnet, 4 power supplys, 5 tongue tubes, 6 relay J, 7 acoustic-optic alarms, 8 base plates.

Embodiment

The invention will be further described below in conjunction with accompanying drawing and embodiment.

Embodiment 1, as shown in Figure 1, having provided the circuit theory diagrams of embodiment 1, it comprises bracing frame 1, cycloid 2, magnet 3, power supply 4, tongue tube 5, acoustic-optic alarm 7.Shown bracing frame 1 fixes with base plate, and the shape of bracing frame 1 is unfixing, can make multiple shapes such as factory's shape, C shape; The top of bracing frame 1 is connected with magnet 3 by cycloid 2, if base plate when vibrations, the swing of certain angle will take place magnet 3, promptly forms induction installation to earthquake by bracing frame 1, cycloid 2 and magnet 3.Warning circuit is made up of power supply 4, tongue tube 5, acoustic-optic alarm 7, tongue tube 5 be arranged on magnet 3 under, tongue tube 5 is connected on the two ends of power supply 4 after connecting with acoustic-optic alarm, in the form place in circuit of tongue tube 5 with normally closed point; Power supply 4 is a direct supply, can adopt two joints No. 5 or No. 7 powered battery.When earthquake takes place, because the swing of base plate 8, will drive bracing frame 1 swings, can make magnet 3 away from tongue tube 5 at last, tongue tube 5 just becomes closure state by off-state, whole warning circuit forms path, acoustic-optic alarm 7 carries out sound and light alarm, the reminds people earthquake is coming, at this moment, people can hand alarm and flee from, and the light source that alarm sends can be used for illumination, even the people that hand-held alarm is fled from is buried in the ruins, rely on audible alarm also can make the rescue worker find buried person in the very first time.

Embodiment 2, set up relay J 6 in the present embodiment, make circuit have auto-lock function, can realize continuous alarm.Identical among induction installation in the present embodiment and the embodiment 1, different is warning circuit, a relay J 6 and 220 volts of alternating currents of power supply 4 employings have been increased in the warning circuit of present embodiment, as shown in Figure 2, shown tongue tube 5 be arranged at magnet 3 under, tongue tube 5 is in parallel with acoustic-optic alarm 7 after connecting with the coil of relay J 6 again, and normal battle of the J1 of tongue tube 5 and relay J is in parallel, and normal battle of the J2 of acoustic-optic alarm 7 and relay is in series.The principle of work of the earthquake warner of present embodiment: when earthquake takes place, at first swing takes place and makes tongue tube 5 become closure state by off-state in magnet 3, this moment, the loop at relay J place formed path, the coil that is relay J gets, make relay J normal battle J1 and J2 all closed, at this moment the also conducting of loop at audible-visual annunciator 7 places, audible-visual annunciator 7 is realized sound and light alarm.By in circuit, setting up relay J, make warning circuit have auto-lock function, even once more near tongue tube 5, making dried spring do 5, magnet 3 disconnects, also warning that can audible-visual annunciator 7 stops more convenient the use.
